Q: Why does
WS-Discovery allow a Target Service to send a Hello without any transport address(es)?
A: To give the Target Service fine-grained control over what it publishes, to support (very) late binding, to support other address-resolution mechanisms, and to minimize packet size.
Q: If a network includes a Discovery Proxy and if a Target Service chooses not to include transport address(es), how does the Discovery Proxy get the transport address(es) to hand out to Clients?
A: A Discovery Proxy could send a multicast Resolve to the Target Service. Of course, there may also be Discovery-Proxy specific means to determine Target Service transport address(es).
